I voted "I don't Know" because I don't ; and it seemed rude to just vote no!
As an armchair enthusiast, I'm very excited by the possibility of such a connection. But, you have pointed out that just because one can walk among 21 pylons out in Egypt-land, it doesn't automatically follow that there is a connection with 21 tarot-type trumps [plus the Fool, of course!].
I am quite fascinated by the work and brute labor of Mark Fillipas in this regard. I am neither a linguist nor a student of the Hebrew Talmud or Torah so I cannot speak to the accuracy of his findings but they seem really compelling to me, not to mention rather elegant!
On the other hand, just because one can find words beginning with alef for every item appearing on a particular card, it doesn't mean that one could not also find words beginning with gimel to describe the same objects on the same card.
I imagine that scores of tarot decks have been purpose built with a connection to the Hebrew Alef-bet, and hundreds of their clones too! But was the first deck, or first several decks? I just don't think so.
I do think that this is the perfect forum to ask and explore these questions. I also know that other theories are strongly held, and evidence often shared.
Thank you, Mary, for giving us this opportunity to share our opinions on this topic.
